## Material selection guide

Start with the material identity and process, then check the details on the proposed datasheet.

**Compound identity**

Provide the formula, elemental ratio, dopant and intended phase. Similar names may describe a different stoichiometry or crystal form.

**Purity & preparation**

State critical impurities, oxygen/moisture requirements, particle profile and the intended thermal or deposition process.

**Packaging & destination**

Use the material-specific SDS to discuss handling, atmosphere and shipment. A semiconductor application does not establish an electronic-grade certification.

## Before you choose

**Does a semiconductor material name imply semiconductor-grade purity?**

No. The application label and an analytical grade are different statements. Define the impurity limits and evidence required for your process.

**What does this directory cover?**

Wafers, ingots, sputtering targets and deposition services are not powder supply entries on this page.

## What to include in your request

A material name or reference datasheet is enough to start. Add any requirements you already know.

- Exact formula, stoichiometry and phase
- Dopant and critical impurity limits
- Particle profile and intended process
- Atmosphere, SDS, use and destination

### Quantity, samples and documents

Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums.

We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements.
